Quick Answer: What Is N5 Nickel?

N5 (GB/T 5235 / Ni 99.8) is commercially pure wrought nickel with Ni+Co >=99.8%, positioned between the ultra-high-purity N4 (>=99.9%) and the standard purity N6 (>=99.5%). It is the workhorse grade for nickel electroplating anodes, electronic lead wire, and general corrosion-resistant components where the extreme low-iron specification of N4 is not required. Shanghai Hangbo Alloy Group supplies N5 as round bars, cold-drawn wire, and strip.

Product Overview

N5 is the balanced purity grade in the Chinese pure nickel standard system. It provides 99.8% minimum nickel content at a cost typically 5-15% lower than N4, making it the preferred choice when the application's iron and copper tolerance exceeds 0.04% and 0.015% respectively.

N5 is most commonly used for:

  • Plating anodes: The controlled iron/sulfur content ensures uniform anodic dissolution without generating excessive anode sludge.
  • Electrode lead wires: The high electrical conductivity of pure nickel combined with corrosion resistance in alkaline environments.
  • Chemical process equipment linings: Cost-effective alternative to N4 for mild alkaline service where trace iron does not contaminate the product.

Shanghai Hangbo Alloy Group supplies N5 in all standard wrought forms with full EN 10204 3.1 certification.

FAQ

Q1: N5 vs N4? N5 has 99.8% Ni vs 99.9% for N4. Iron 0.10% vs 0.04%. N5 saves 5-15% cost for applications tolerant of slightly higher impurities.

Q2: N5 vs NI200? N5 has higher purity (99.8% vs 99.0%) and lower iron/carbon. Equivalent to the "LC-Ni" grade in Western markets.

Q3: Price? $25-42/kg EXW. Contact sales@hangboalloy.com.

Q4: Forms? Round bars, wire (0.1-10mm), cold-rolled strip (0.1-3.0mm). SGS available.

Q5: Weldable? Yes, with ERNi-1 filler.
